Add php code inside the function add_shortcode in functions.php Wordpress

Question

How I can add php code inside the function add_shortcode in functions.php

For Example:

<?php $images = get_field('img_novinki'); if( $images ) { ?>


<div id="carousel" class="flexslider">
    <ul class="slides gallery">
        <?php foreach( $images as $image ): ?>
            <li>
                <a href="<?php echo $image['url']; ?>"><img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" /></a>
            </li>
        <?php endforeach; ?>
    </ul>
</div> <?php } ?>

Shortcode in functions PHP:

function my_novinki( $atts ) 
{
    return '';
}
add_shortcode( 'my_novinki', 'my_novinki');

I'm not sure I understand your question. The function add_shortcode is to create a shortcode, in this case it would be called using [my_novinki]. Then the code inside the function also named my_novinki will run. — Neil K

See Codex: "..the function called by the shortcode should never produce output of any kind. Shortcode functions should return the text that is to be used to replace the shortcode."

You need to wrap your code in ob_start() and ob_get_clean():

add_shortcode( 'my_novinki', function my_novinki( $atts ) {
    ob_start();
    $images = get_field( 'img_novinki' );
    if( $images ) { ?>
        <div id='carousel' class='flexslider'>
            <ul class='slides gallery'> <?php
                foreach( $images as $image ) { ?>
                    <li>
                        <a href='<?php echo $image['url']; ?>'>
                            <img src='<?php echo $image['sizes']['thumbnail']; ?>' alt='<?php echo $image['alt']; ?>' />
                        </a>
                    </li> <?php
                } ?>
            </ul>
        </div> <?php
    }
    $out = ob_get_clean();
    return $out;
});

From what I see you will need to do the following. In functions.php add:

function my_novinki( $atts ) 
{
   $images = get_field('img_novinki'); 

   if( $images ) {

    echo '<div id="carousel" class="flexslider">';
    echo '<ul class="slides gallery">';

      foreach( $images as $image ):
            echo '<li>';
            echo '<a href="'. $image["url"] .'"><img src="'.$image["sizes"]["thumbnail"] .'" alt="'. $image["alt"] .'" /></a>';
            echo '</li>';
      endforeach;

   echo '</ul>';
   echo '</div>'; 
  }

}

add_shortcode( 'my_novinki', 'my_novinki');

Then this can be called using [my_novinki] or if in a php template using <?php echo do_shortcode['my_novinki'];

I just checked this code. The problem is that nothing is output. There are no errors in the syntax, but the code does not print anything to the page.

May be my php code is wrong)))) I will check it too.

Maybe the problem is that there is nothing in the $images variable, hence the code inside the if statement doesn't run

Orkhan Hasanli Over a year ago

I think the same))) Thank you so much
